Embodiment Construction

[0023] The energy saving method of CPU VR with a variable phase number of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments (taking 6-phase power supply as an example).

[0024] Such as figure 1 , 2 Shown in and 3: PHASE1, PHASE2, PHASE3, PHASE4, PHASE5, PHASE6 represent phases 1, 2, 3, 4, 5, and 6 respectively, and the power supply end of each phase is connected to the CPU.

[0025] Such as figure 1 Shown: An energy-saving method for CPU VR with a variable phase number. By detecting the current at the load end and comparing the detected current value with the set current value, when the actual current value is greater than the set value, the CPU will be automatically increased. The number of power supply phases of VR; when the actual current value is less than the set value, the number of power supply phases of CPU VR is automatically reduced, so that the load can obtain the optimal conversion effici...

Abstract

The invention discloses an energy-saving method of phase number variable CPU VR (Central Processing Unit Voltage Regulation). The current of a load end is detected, a detected current value is compared with a set current value, the power supply phase number of the CPU VR is automatically increased when the actual current value is larger than the set value, and the power supply phase number of the CPU VR is automatically decreased when the actual current value is smaller than the set value to enable the optimal conversion efficiency to be obtained no matter loads are worked in the condition of light loads or heavy loads.

Description

technical field [0001] The invention relates to the field of power supply for server mainboards, in particular to an energy-saving method for a CPU VR with a variable phase number. Background technique [0002] With the continuous rise of cloud computing technology, the online business volume continues to increase. Higher requirements are put forward for the data processing capability and storage capacity of the server in the computer room. As a unit-cabinet system in a traditional computer room, it is required that the data processing capabilities of the server computing nodes deployed inside the cabinet are getting stronger and higher, and the deployment density is getting higher and higher. The stronger the data processing capability of a computing node, the more data it processes per unit time, and the greater the power consumption of the node; since there are thousands of cabinets in a general large-scale data center computer room, even if a single node saves 1W of pow...
